RESUMO

To investigate mixed convection flows through a nanofluid in a square double lid-driven cavity with various inclination angles and sinusoidal heating on the left wall, a numerical method based on the finite volume approach is applied. In this work, a SiO2−water nanofluid was used. The cavity is nonuniformly heated from the left, Th, and cooled from the opposite wall. The top and the bottom moving walls were supposed to be insulated. The study was performed at the Richardson number from 0.1 to 10, Reynolds number from 1 to 100, and the solid volume fraction of nanoparticles φ altereing from 0 to 0.06. The effects of variations of Richardson and Reynolds number, angle of inclination, and solid volume fraction of nanoparticles on the hydrodynamic and thermal characteristics have been studied and discussed. As a result, it was found that the increases heat transfer rate with the solid volume fraction for a particular Re. The heat transfer rate also increases with the Richardson and Reynolds numbers for a particular volume fraction. The problem of mixed convection flows through a nanofluid in a square double lid-driven cavity with various inclination angles and sinusoidal temperature profiles on the left wall has not been reported so far. The effects of an increase in the shear force or buoyancy force, with another force kept constant, on heat transfer enhancement are studied.
